First time neck sizing. Need help?

Hi. This is my first post on the forum, normally I just lurk and read a lot.

However, I need some help from the more experienced reloaders here. I'm trying to partial neck size some once fired Nosler brass with a Forster bushing bump die. While sizing the necks I'm noticing that there is brass being shaved off the necks. Is this normal? If not, what should I do to stop it?

Thanks for any help.

check to see if your bushing is in backwards

Thank you for replying. I did that several times per Forster's instructions. Chamfered side down.

You may want to get the next size bigger bushing and run it in that first then go back to the bushing your using now. It's just a case of trying to work the neck down gradually rather than force it right in the size bushing you want. This is caused by the chamber neck being a little on the big side, no big deal at all though, that's were tight neck chamber's can cut some corner's

Thanks Dan, I'll try that.

I tried stepping the bushings down and the bushing was still shaving off brass from the necks. I ended up polishing the chamfer of the bushing with my dremel. No more shaved brass. Thanks for the suggestions guys I did not want to go at this with the dremel, however, it worked.

Thanks again.

Good.You may have had a small burr on the bushing.Lube the neck.

I use mink oil to lube the cases when I am full length resizing. Heard about it on another forum and it works very well. That's what I used to lube the case necks.

Glad you figured it out, good job.
